AES解密失败：Given final block not properly 400 请求出错 

AES解密失败：Given final block not properly padded. Such issues can arise if a bad key is used during decryption.

AES解密的时候出错了，加密解密放在一起是没有问题的，但是分开单独一个方法就GG了，求救
------------

代码如下：

public class AESEncryptUtil {

    private static byte[] salt =
        {(byte)0xc7, (byte)0x73, (byte)0x21, (byte)0x8c, (byte)0x7e, (byte)0xc8, (byte)0xee, (byte)0x99};

    public static void main(String[] args) throws Exception {

        // 加密字符串
        String message = "df723820";
        String password = "8679270339387350";

        String a = encryptAES(message, password);
        decryptAES(a, password);
    }

    public static String encryptAES(String message, String password) throws Exception {
        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 65536, 256);
        SecretKey tmp = factory.generateSecret(spec);
        SecretKey secret = new SecretKeySpec(tmp.getEncoded(), "AES");

        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, secret);

        byte[] ciphertext = cipher.doFinal(message.getBytes(StandardCharsets.UTF_8));
        String result = Hex.encodeHexString(ciphertext).toString();
        System.out.println("加密后: " + result);

        byte[] iv = cipher.getParameters().getParameterSpec(IvParameterSpec.class).getIV();
        cipher.init(Cipher.DECRYPT_MODE, secret, new IvParameterSpec(iv));
        byte[] decryptStr = cipher.doFinal(Hex.decodeHex(result));
        System.out.println("同一个class里解密: " + new String(decryptStr, StandardCharsets.UTF_8));
        return result;
    }

    public static void decryptAES(String message, String password) {
        try {
            SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
            KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 65536, 256);
            SecretKey tmp = factory.generateSecret(spec);
            SecretKey secret = new SecretKeySpec(tmp.getEncoded(), "AES");

            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            byte[] iv = cipher.getParameters().getParameterSpec(IvParameterSpec.class).getIV();
            cipher.init(Cipher.DECRYPT_MODE, secret, new IvParameterSpec(iv));
            byte[] decryptStr = cipher.doFinal(Hex.decodeHex(message));
            String result = new String(decryptStr, StandardCharsets.UTF_8);
            System.out.println("不同一个class里解密: " + result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

运行结果：
